Mysql is a relational database. It has many keywords for users to use to manipulate data. For example, I will introduce order to you today. Its expression in mysql is generally order by.

What does order mean?

When you use the SELECT statement to query data from a table, the result set is not sorted in any order. To sort the result set, use the ORDER BY clause. The ORDER BY clause allows you to:

Sort the result set by a single column or multiple columns.

Sort the result set by different columns in ascending or descending order.

The following introduces the syntax of the ORDER BY clause:

SELECT column1, column2,...
FROM tbl
ORDER BY column1 [ASC|DESC], column2 [ASC|DESC],...
Copy after login

ASC represents ascending order, and DESC represents descending order. If no collation is specified, the order by clause sorts the result set in ascending order by default.
